      var arraywithvaluesandgroups = [{             "testobject": "object1",             "graphgroup": {                 "test": {                     "group": "a",                     "value": "6"                 },                 "test2": {                     "group": "b",                     "value": "5"                 }             }         },          {             "testobject": "object2",             "graphgroup": {                 "test": {                     "group": "a",                     "value": "9"                 },                 "test2": {                     "group": "b",                     "value": "12"                 }             }         },          {             "testobject": "object3",             "graphgroup": {                 "test": {                     "group": "a",                     "value": "99"                 },                 "test2": {                     "group": "b",                     "value": "16"                 }             }         }     ]

i want create new object groups , values have group should in array. example want above object converted bellow

     {         "a": {             "test1": {                 "0": "6",                 "1": "9",                 "2": "99"             }         },         "b": {             "test2": {                 "0": "5",                 "1": "12",                 "2": "16"             }         }     }

what strategy use?

try this.

concept of object , array important on js , code.

practice way.

var newobject = {};   for(var i=0,ilen=arraywithvaluesandgroups.length;i<ilen;i++){      var testgroupobject = arraywithvaluesandgroups[i];      console.log(testgroupobject);       // {      //    "testobject": "object1",      //    "graphgroup": {      //        "test": {      //            "group": "a",      //            "value": "6"      //        },      //        "test2": {      //            "group": "b",      //            "value": "5"      //        }      //     }      // }       var graphgroupobject = testgroupobject.graphgroup;      console.log(graphgroupobject);      // {      //        "test": {      //            "group": "a",      //            "value": "6"      //        },      //        "test2": {      //            "group": "b",      //            "value": "5"      //        }      //     }       var graphgroupobjectkeys=object.keys(graphgroupobject);      for(var j=0,jlen=graphgroupobjectkeys.length;j<jlen;j++){          var graphgroupobjectkey = graphgroupobjectkeys[j];          console.log(graphgroupobjectkey)          // keys test, test2           // graphgroupobject[graphgroupobjectkey]          // {          //     "group": "a",          //     "value": "6"          // }           var group = graphgroupobject[graphgroupobjectkey].group;          var value = graphgroupobject[graphgroupobjectkey].value;           if(!newobject[group]){              newobject[group]={};          }          if(!newobject[group][graphgroupobjectkey]){              newobject[group][graphgroupobjectkey]={};          }          newobject[group][graphgroupobjectkey][i] = value;      }  }
